Test Run

After using the Setup Wizard to make settings for the basic parameters, and Auto-Tuning of the motor has been
completed, the next step is to perform a test run.
WARNING! Crash Hazard. Conduct test operations to make sure that the drive operates safely after writing work is completed
and parameters have been set. Failure to comply may cause injury or damage to equipment.
◆

No-Load Test Run

Before connecting the motor with machinery, check the operation status of the motor.
■

Load Shaft)
6.
Raise the frequency reference value by pressing
Change the setting value in increments of 10 Hz if needed while evaluating the response.
7.
Check the drive's output current using U1-03 [Output Current] each time the setting value is raised.
The status is normal if the output current of the drive does not exceed the motor rated current.
Ex.: 6 Hz → 20 Hz → 30 Hz → 40 Hz → 50 Hz → 60 Hz
8.
After confirming that the motor rotates normally, press
The RUN indicator will be flashing. Then, when the motor is completely stopped, it will go out.
